"""Fetch set19 .kicad_pcb sources listed in manifest_set19.json (raw download).

Mirrors fetch_set10.py. Downloads each board (and its sibling .kicad_pro, which
carries the DRC floor) into $STRESS_DIR/sources/github_set19/.
After fetching, run `bash prep_set19.sh` (needs KiCad's bundled python /
pcbnew) to produce boards_set19/ (routed reference) +
boards_unrouted_set19/ (stripped).
